SPRAYING MACHINE.

App1cation filed May 16, 1923.

To all '1r/0171. it may concer/n:

Be it. known that l. JOHN H. J. Arsenic. a citizen ot' the ilnitedStates, and a resicent of Mount Pleasant. in the county ot Charlestonand State ot South Carolina. have invented certain new and usefulImprove ments in Spraying Machines, of which the 'Following is aspecilication.

My invention` relates to improvements in spraying machines and itconsists ot the constructions. combinations and arrangements hereindescribed and claimed.

An object ot' the invention is to provide a machine tor spraying asuitable poisonous liquid upon cotton plants tor killing boll weevils.

A. further object oi' the invention is to provide a spraying machinehaving sets ot sprayers arranged to spray the liquid both at the sidesand tops of cotton plants in more than one row at a time.

A further object of the invention is to provide a spraying machinecomprising a sulky upon which the spraying apparatus is mounted thesulky being adapted to be driven. over the rows of cotton plants, thespraying apparatus being so arranged as to reach the plants in more thanone row at a time.

Other objects and advantages will appear in the following specification,reference being had to the accompanying drawings, in which:

Fig. 1 is a rear elevation of the improved spraying machine,

Fig. 2 is a side elevation,

Fig. 3 is a detail perspective view of the spray head,

Fig. i is a detail cross section of one of the blowers takensubstantially on the line 4 4 of' Fig. 1, and

Fig. 5 is a. detail section ot the liquid cask, taken substantially onthe line 5-5 of Fig. 1 and showing the agitators inside.

In carrying out tl e invention7 provision is made of a sulky upon whichthe spraying apparatus is mounted and upon which it is transported overthe fields of cotton plants, The sulky comprises a iframe 1 whichincludes pendent bearing straps 2 which engage the downwardly bentportions of a bar 3 in such a manne-r as to hold this bar steady. Thedownwardly bent portions of this bar are bent outwardly and provideaxles i upon which the sulky wheels 5 are journalled.

Serial No. 639,433.

,fi countershatt 6, journalled on hangers 'T which are pendent troni theframe 1. is riven by a chain S which is applied (o 'octets 9 and l() onthe countershatt l attached to the hub ot' one ot the wheels rllhecountershatt G carries a large spuieir 1l. which meshes with a smallergear 12 on a blower shatt This shaft is suppor'ed by bearings 14e.

The conntershatt G also carries a sprocket nfliich drives a chain 16.This chain is applied to a sprocket 17 on the sha-ift 18 of a pluralityof agitators 19 in a cask 20. Preierably there are two agitatorsopposite each other and suitably perforated to aid in mixing the liquid.The agitators are adapted to stir the liquid L (Fig. 5) so as to keepany constituents which are likely to settle at the bottom in suspension.Referring again to the shaft 13. it is to be observed that this shaftextends through a pair of blower cases 21 and 22 (Fig. 1). In each ofthese casings there is a blower 3 as shown tor example in 4.

it downwardly directed nozzle 24 `from each blower casing causes the airto be cirecte-d toward the plant. It is to be observed that the gear 12(Fig. 2) is smaller than the driving gear 11. This particulararrangement is 'for the purpose of gaining speed ot rotation at theblowers. In actual practice, the ratio between the gears 11 and 12 maybe even greater than suggested by the drawings so that the blowers maybe made to move correspondingly faster. rThe blower casings 21 and 22are supported upon the frame 1 in any suitable manner.

Connecting with the bottom of the cask 2O is a main spray pipe 25 whichhas communication with laterals 26 and 27 at a 4-way connection 28. A.pipe 29 is screwed into the remaining outlet ot this connection. Thepipe 29 is practically a continuation of the main spray pipe 25. Tt,like the pipe 25. has lateral 30. The laterals ot the main sprayl pipe25 and extension pipe 29 have spray cups 31 and 32 which are severallyso positioned as to insure applying the poisonous liquid well on top andat the sides ot the plants P over which the machine is driven. Those ofthe spray cups on the front line are round but those in the rear areoblong so as to more readily cover they tops ot the plants. All of thespray cups are adjustable to any desired angle.

It is to be observed in Fig. 3 that the sp1. i i n d various spray cupsare arranged in two sets in such a manner that the plants in two rows otcotton can be tre-ated at one time (see Fig. l). Circumstances mightarise when it might not be desired to perinit the escape Qt liquid atthe inner spray cups For this purpose, the extension pipe 29 is tittedwith a globe valve 35% by means ot which the iiow ot liquid to theseIparticular cups is cut ott. A valve 34 in the pipe permits cutting ott'the tiow of liquid trom the casl. This valve is controlled by aconnection which is within reach of the operator.

The sullry is adapted to be drawn by horses, a draw bar 341; (Fig. beingprovided tor the purpose. fr seat 35 is provided 'tor the driver, thisseat being shown in Fig. i2, but the showing thereof being omitted iiiFig. l. The operation ot the sprayer is doubtless quite obvious from the'foregoing description and from the drawings. However, a briei reviewmay be or' advantage,

The sullry is drawn over the cotton plants P, the wheels being tarenough apart to permit reaching` the plants in two rows at one time. Thespray head in Figs. l and 3 is also arranged to carry out this purpose.The spray oups 3l and S2 are arranged in two sets and are disposed toi'ace each other iu the manner shown so that the liquid may be appliedto the plants substantially from the top (Fig. 2) and from the lateralsides.

As the spraying machine progresses along the cotton rows, the blowers 28in the casings 21 and 22 are driven `at a high rate oi speed and blastsof air are discharged at the nozzles .24- upon the plant in advance o'l'the spray head. These blasts ot air serve to spread the enfolding leavesof the cot-4 ton form and young bolls so that the liquid may penetratemore 'deeply when reached by the spray head. As has been mentionedbefore, the communication oi: the liquid with the inner spray cups 32may be cut olii by closing the valve (Fig. 3). The supply ot liquid L(Fig. 5) is replenished by removing t-he plug at the top oi the Cask andpouring in a fresh supply.

Reference is again made to Fig. S. i't is vto be observed that the sprayoups 3l, respectively situated along the back ot the pipe 25 and at theconfronting ends, are mounted by means of fittings 36 and 37.

The latter are elbows which `ioin the long back pipe 25 with the shorterends 38. These in turn are connected, by means oiC elbows 39, with theshort pipes 40 which carry the aforesaid confronting cups.

The purpose of this arrangement ot {ittings is to provide considerablelatitude 'for adjustment. The cups 3l may be adjusted at any desiredangle, either singly or collectively. The object ot this is to insurethat the spray will reach any.'Y desired part of the. plants.

`While the construction and arrangement oct the improved sprayingmachine as herein described and claimed, is that of a generallypreferred "form, obviously modifications and changes may be made withoutdeparting from the spirit of the invention or the scope of the claims.

. claim l. ri spraying machine comprising a traine, wheels upon whichthe trame is mounted including axles upon which the wheels turn, acounter shaft, means by which the counter shaft is turned from one otthe axles, a caslr mounted on the frame, agitating means in the Cask,meansby which the agitating means is operated from the counter shaft, aspray head including a spray pipe in communication with the cash andspray cups carried by the pipe tor applying' the liquid to plants as themachine is drawn thereover, a blower shaft mounted on the trame, meansby which the blower shaft is 'driven from the counter shaft. blowercasings through which the blower shaft extends the shaft having blowersmounted thereonV in said casing, and a blower nozzle extending trom eachcasing;l in advance ot Ythe spray head the: blasts ot air being adaptedto open the bush to permit a thorough penetration oi"V the sprayedliquid.
